Not everyone is the same. I did four cleanses, and I used enemas and not the SWF, even though the book was against it. I used just one of Schultz's lax pills at night. The SWF (Salt-Water-Flush) felt like I was just going to vomit it back up. I think everyone has to work this out individually. I did not have the runs and other things to hinder my daily living.
